dc.description.abstractThe survey of freshwater snails carried out in Zaria area, Nigeria, from July 1990 to June 1991, using 10 to 15 minutes man sampling method, revealed five species of snails, thus, Bulinus globosus, Morelet; Biomphalaria pfeifferi, Krauss; Lymnaea natalensis, Krauss; Bulinus forskali,Ehrenberg; which are pulmonates, and a species of prosobranch, Melanoides tuberculata, Miller. The distribution of these snails varied because the differ in tolerance of pH, temperature, vegetation and habitats. Temperature and pH ranges observed during the study, fall within the ranges required for snails survival and development. The mean values of the measurement of furcocercous cercariae shedded by L. natalensis, B. globosus and B. Pfeifferi correspond to cercariae of Schistosoma bovis, S. haematobium and S. mansoni respectively. B. forskali under laboratory conditions was not susceptible to Schistosoma haematobium miracidia infection.en_US
